Abstract

PURPOSE:To make a shoulder section beautiful and to enhance the bonding strength between a barrel section and the shoulder section, by pinching the barrel section and the shoulder section between a receiving jig and a tool horn, and causing ultrasonic vibrations of the tool horn so that the lower welding margin, the barrel tip and the upper welding margin may be welded by the ultrasonic welding. CONSTITUTION:A receiving jig 8 is formed with a female mold having an outer diameter corresponding to a shoulder section 4 of a conical body 7 and is lowered to fix the shoulder section of the conical body 7. A tool horn is elevated through the inside of a barrel section 1 until it is abutted against the lower welding margin 6 of the shoulder section 4, so that the lower welding margin 6, the barrel tip 1a and the upper welding margin 5 are pinched firmly between the receiving jig 8 and the tool horn 9. A support plate 10b is drilled to have an opening 10c through which the tool horn 9 can be elevated. Then the tool horn 9 is caused to have ultrasonic vibrations thereby vibrating the lower welding margin 6, the barrel tip 1a and the upper welding margin 5 vertically so that frictional heat may be generated between the contacted surfaces thereby fusing the barrel section 1 and the shoulder section 4.

溶着方法は、射出成形法。■ Conventional Techniques Conventionally, when manufacturing multilayer tubes made of polyethylene, polypropylene, etc., or laminate tubes with two sheets of aluminum foil inside, injection molding is the method used to weld the body and shoulders.

しかしながら、これらの溶着方法は大規模な機械設備が
必要であり、かつ機械自体が複雑であるという欠点があ

非常に困難であり、その上。However, these welding methods require large-scale mechanical equipment and have the disadvantage that the machines themselves are complicated. Furthermore, it is extremely difficult to completely weld the joint between the torso and shoulders.

溶着時の熱により樹脂が黒変し外観上肩部の美感を損ね
る欠点があった。There was a drawback that the resin turned black due to the heat during welding, spoiling the aesthetic appearance of the shoulder area.

そこで、このような不都合を解消するために開発された

着時間が短くかつ樹脂の劣化を起こさないで均一で強力
な接合力が得られる点である。Therefore, as a method of welding the two torso parts and the shoulder part, which has been developed in order to eliminate such inconveniences, there is a welding method using ultrasonic vibration. The advantage of this welding method using ultrasonic vibration is that the welding time is short and a uniform and strong bonding force can be obtained without causing deterioration of the resin.

超音波溶着法の従来技術としては２例えば第５図および
ｆｆ４６図に示すようなものがある。図中。There are two conventional techniques for ultrasonic welding, such as those shown in FIGS. 5 and 46, for example. In the figure.

a is formed. The body part 52 is fitted onto the outer periphery of a cylindrical receiving jig 53 having an outer diameter that is approximately the same as the inner diameter of the body part 52, and the body part welded end 52 is fitted onto the upper end of the body part 52.
a is formed, and this body welded end 52a is attached to a receiving jig 53.
It protrudes slightly upward from the upper edge. Next, the cylinder 50 is seated on the edge of the receiving jig 53 inside this protruding part, and then the tool horn 54 having the outer shape of the shoulder 51 is lowered onto the shoulder 51 to apply pressure. The body part and the shoulder part are welded by folding the part welding end part 52a over the shoulder part welding margin 51a and applying ultrasonic vibration to this overlapped part.
